1. The layers of OSI model are: Physical Layer, data link layer, network layer, transport
layer, session layer, presentation layer and application layer.
The layers of TCP/IP model are: network access layer, internet layer, transport layer, and
application layer.
2. The data link layer and the physical layer of the OSI model represents network layer
TCP/IP model. The network layer represents the internet layer of the TCP/IP model. The
transport layer of both the models are same (Zseby et al., 2016). Three layers of OSI model that
is session layer, presentation layer, and the application correlates the application layer of the
TCP/IP model.
3. Physical layer, Data Link layer, and the Network layer of the TCP/IP protocol are the
network support layers of the model. The network layer is also known as the internet layer that
deals with many packets of data and connects all the networks independently for transporting
packets across the network boundaries (He et al., 2016). The Session layer, Presentation Layer,
and the Application layer are the user support layer of TCP/IP protocol.
4. Encapsulation in networking states as a process that takes data from a particular
protocol and then translates the data in to another protocol. This is done so that the data can be
moved from one network to another. Data encapsulation can also be defined as sending of data to
different layers of the network.
5. The responsibility of data link layer is to provide link control, media access control,
error detection, handling the physical layer, defining the physical layer, and addressing the
